Option 1- Just because someone reads and doesn’t post doesn’t mean that don’t agree or aren’t prolife. It just means that they see this as superfluous on a predominantly Catholic forum. If I see someone has already answered something better or the same as I would, I typically bow out and move on to the next post. In the case of this topic, there’s really nothing people can add other than Amen? I would have fallen into this category, but I didn’t want you to doubt the faith of others based on the fact that they have not responded.
Option 2- Also, you addressed a Catholic question to everyone, including non-Catholics. They’re probably scratching their heads and thinking, “How am I supposed to know the true answer to this? I’m Prolife, but not Catholic. I guess Catholics can’t be prochoice and catholic???” If you wanted a greater response from others, you should word it so that others can feasibly apply to all religions. Maybe something like, “Abortion is morally wrong” or “Abortion sucks the life out of women”.
It’s just my personal observations. Feel free to listen or disregard them as you like.
Peace be with your spirit.
